DRAFT-TUBE 'FOR SODA-WATER AND- OTHER BEVERAGES.

SPECIFICATION forming part of Letters Patent No. 257,472, dated May 9, 1882, Application filed November/4, 1881. (No model.)

To all whom it may concern:

Be it known that I, WM. P. CLARK, of Medford, State of Massachusetts, have invented an Improvement in Draft-Tubes 'for Soda-Water and other Beverages, ot' which the following is a specification.

This invention relates to certain improvements in the drafttube for'which Letters Patent of the' United States No. 229,804 were issued to me June 29, 1880, and the invention will, in connection with the annexed drawings, he hereinafter fully described, and specifically defined iu the appended claims.

Figure l is a perspective view of a drafttube embodying my present invention. Fig. 2 is a longitudinal vertical section thereof. Fig. 3 is a detached view, showing in perspective the upper portion of the vertical regulating and shut-oft valve-stem and in vertical section the hand-wheel by which such stem is actuated, thereby showing the method of connecting such stem and wheel. Fig. 4i is a transverse section as on line z, Fig. 1, and showing the lower face of the valve in plan, the wall in section, and method ol' interlocking the valve and wall. Fig. 5 is a detached perspective view, showing the draft-valve, its delivery-nozzle, the valve sleeve, and the 1 valve-lever. Fig. 6 is a vertical sectional elepacking-holder with the packing therein inter- 4 locked by my improved method.

. In said views, AA represents the marble slab or other vertical support to which the drafttube is to be attached.

B is the body of the draft-tube, which is secured to slab A by shank a, which passes through the ornamental collar C and said slab, and is secured in position by the screw-nut b in the usual manner.- Said shank a. is formed with an axial passage, e, in the usual manner, which communicates with the passage in the supply-pipe, that may be coupled to said shank. The passage ein shank a extends forward in bodyB and terminates as the axial passage in the vertical nipple c, which is arranged at the bottom of a transverse vertical passage in body B, which passage is in part formed by the iiow of liquid through nipple c, and also regulating the dow of the liquid through passage g when the same is in use, I employ a valve constructed as follows:

The valve 'i and its stemj are united by a left-hand thread, as shown in Fig. 6, and upon head of the valve is formed a stud, r, which interlocks in a groove in the wall d, which incloses the valve. (See Fig. 4) Upon stem j is formed a rigid collar, m, below which and next valve i is placed the loose metallic collar fn, while an elastic collar, o, is seated between said metallic collars,as shown in said Fig. 6. In cap s, which is threaded upon walls d, is seated an elastic washer, t, which, when the severalparts are in position, iscompressed upon the upper edge or rim of wall d, and upon the rigidcollar m of stem j, while collar n is seated upon a shoulder formed in wall d by enlarging the upper portion of the valvechamber therein, (see Fig. 2,) whereby the turning down of cap s packs washer t upon collar m and wall d, and shuts oft' the escape of liquid between the collar and wall, while the elastic collar 0 is expanded against the interior of wall d, thereby tending to pack the space between the rigid collars on stemj and said wall, and also causing loose collar u to be firmly seated upon the shoulder in said wall, and yet to move thereon when the stem is rotated without grinding and wearing such col-` lar and shoulder. By turning stemj in a lefthand direction its valve i is raised to allow the flow of the liquid through nipple c, and by adj ustin g the lower end or face ot' said valve rolatively tojpassage g thesame may be opened to anydesred extent, and as said passage is arranged to deliver the so called sharp stream it may thus be adjusted with reference to the `degree of pressure in the supplyfountain, and when the valve is thus raised the passagefis open to deliver the flat stream whenever brought into requisition. The valve fi is not usually further moved than lnerely to govern or adjust the force of the sharp stream, as just specified, as the outer valve is used to shut oif the flow of liquid, as will be described; but should it be necessary at any time to adjust such outer valve, then by actuating stem jvalve t' is, by the means described, moved down, so as to seat its central packing, p, upon nipple c, thereby shutting off the further iow ot' the liquid.

For the purpose of actuating.;` stemj and its valve t' a hand-wheel cap, D, is removably secured thereon in the manner shown in Fig. 3, which consists in forming said stem with a diminished round upper section, 3], and next thereto a rectangular section, x, while in cap D is formed a corresponding interior cylindrical cavity, b', andjust within the body ot' the cap a corresponding square passage, a', while between said round and square passages is formed an enlarged chamber, e, by which eon-. struction of parts great facility ot' construction and efficiency and convenience in use are effected, as a cylindrical passage is first form ed replaced on-the stem when desired.

The passagesj'g extend in body Btc the transverse passage for the packing-holder h, and packing u in holder h is provided with passages coinciding with said passagesfg, as shown in Figs. 2, 7.

A sleeve, d', is seated in the front portion of' body B, as shown in Fig. 2, and is interlocked therewith by its stud c', which seats in a groove in body B. The valve c and a portion of the length of its stein u: are seated in said sleeve d and partially rotate therein, such rotation ybeing 'effected by lever j", which is secured on said stem, and which is provided with a check-pin, g', which, by its contact with stops It h in sleeve d', adjusts the position otl of curved nozzle 'i' ot' stem u either up or down, as desired, as is fully described in my said former patent. A removable face is secured to valve QJ by an axial screw, as shown in Fig. 2, and a passage, c', is formed therein at the same distance from its axis as are passages fg, so that when said valve is so rotated as to turn nozzle fi downward said passage in the valve is coincident with the sharpstream passage g, and when said nozzle is turned upward said valve-passage is coincident with the dat-stream passage f. Said passage c is deflected to the axis ot' valve o and extends through the same and through nozzle i', as in my said former patent.- The sleeve elf-and valve 'v are held in the requisite close contact with packing u by means of cap j,

which is threaded on body B, and acts against shoulder 7c of sleeve d', the interior counterpart of which shoulder bears against packing l', which is placed ou stem fw of valve c, as shown in Fig. 2. Upon said cap j', as also upon cap s, are formed the radial ornamental arms I, which furnish the ever-ready means ot' actuating said caps without the use of wrench or spanner, and whichobviate the necessity of disiiguring said caps by a Spanner-hole, or of forming them with angles by which to engage an actuating-wrench.

llhe spraying-glass m', within which nozzle t" is located, is secured in band u of rod o', said rod being secured upon studs p' r', which extend from body B, said stud p passing through the rod and being provided with a screw-nut, s', which secures the rod in position, the stud r serving to secure the rod from lateral vibration on stud p. This method of securing said rod is preferable to that shown in my former patent in that one nut serves to secure the rod in place, and the two studs not 4 only secure it from lateral displacement, but the stud r serves as a fulcrum to prevent dcpression ot' the outer end of the rod, which supports the glass m.

The packing-holder h is formed with the usual circular passage for the insertion ot packing u; but said holder is also formed with a projection or seat extending from said passage to receive the corresponding projection, t', of packing a, whereby said packing is prevented l'rom rotating in the holder when valve c is rotated.

I claim as my inventionl. The combination ot' valve-stemj, its head z', threaded thereon and arranged to interlock in wall d, the rigid collar m on said stem, the loose metallic collar n, and elastic packing o, arranged between said collars, substantially as specified.

2. The combination of valve-stem j, its interthreaded head i, collars on a, packing 0,' and cap s, with its packing t, arranged to seat upon both said collar m and the rim ofthe inclosing-wall d, substantially as specified.

3. The combination of valve z', the inlet-conduit c, arranged to be closed and opened by said valve, and the outlet-passagesfg, connecting with the valve-chamber and provided with mechanism whereby either of said passages may be rendered operative andthe other inoperative, or both be rendered il'ioperative, substantially as specified.

4. The combination ot' valve fi, conduit c, conduitsfg, and rotary valve e, having a longitudinal passage arranged to be brought into coincidence with either ot' said conduitsfg, substantially as specified.

5. The rigid packing-holder It, formed with a recess or seat extending outside the circumferential lille of the packing-passage therein, and the packing u, formed with a corresponding projection, t', to interlock in such seat in the holder, substantially as specified.
